Procaterol metered-dose inhaler in adults with asthma

Procaterol hydrochloride is a new sympathomimetic amine which is highly selective for beta-2 receptors. The drug has been previously studied in the oral dosage form and has been found to be an effective bronchodilator with a prolonged duration of action. The present study evaluated the procaterol metered-dose inhaler (in comparison to placebo) in 30 adult patients with asthma during a 2-week treatment period. The drug was shown to be an effective bronchodilator with a prolonged duration of action.
